Be it known thatI, JOHN WI SIDEBoTToM,

of Lowell, in the county of Middlesex and the Commonwealth of Massachusetts, have invented certain new and useful Improvements in Lease Forin'ers, of which the following description, with the accompanying drawing, is a Specification.

This invention relates to Lease-Formers and to lease-combs having a dent having an eye for carrying a thread sometimes above and soinetiines'below another thread, T The invention lies inthe construction of a dent having a spiral-eye and in its combiparts, as is set forth in the I .a partial elevation looking laterally of the comb." Figs. 2, 3, and 4: are partial elevations looking longitudinally of the 'conib and showing the comb in its highest, niddle,land. lowest positions, respectively. -'FigL 5 is an elevation of a detail looking in a direction which is theopposite to that of Figs; 2, 3, and 4. Fig, 6 is an elevation of a detail corresponding in direction with Fig.1." Fi -7 is a cross-section taken at line 7 of hi0. 6.- Fig. 8 is a cross-section taken at lin gig of Fig.6. it

Inthe drawing, 1 andl arestationary brackets secured to the framing (notshown) of a lease-warper. Eachbracket' has a vertical slot 2, the front and rear side walls of which guide the comb-box 3 as itmoves up and down. 7 Stops t 4 fastenedto the'b'ox and sliding up and downalon'g'side the brackets serve through engagement with the sides of the latter to prevent endwise movement ofthe box. The box extendsbeyond the brackets and is supported at both ends by'wedge-shaped cams 5 5 connected to-' gether by a rod 6 to which 'theyare setscrewed to make them fast therewith. One

three rests 9, 10, and 11 for contact with a support 12 constituted by thebottom pop tion of the bracket. The inclined faces 13 and 14 connect the rests and slide uponthe; upport 12 during themotio'ns of the foam.

Horizontal motions oft-he camscause vertical positions of "the combi'are shown in the draw ngs, viz: in Figs 1 and 2, inthe highest position, as when the rests 9 9areon the cal motions of thebox, The different verti- 0 u u l g supports 12 12; in Fig. 3 111 the position of intermediate height, as when the rests 10 10 are on those supports and in Fig. 4: in the lowestjposition, as when therests 11] 11 are i onthem. The comb has the springs 15115 and other usualappurtenances of an expan-' sioncomb'operating to hold its dents from turning orrotating. Supported between the coils of the Springs, inusual 'rnan'nenfare fiat-wire dents '16 alternating with dent 17 i of my invention. Each dent -17 has'a' body l8of flat wire which" is identically like a dent 1-6. soldered to this body at a distance from its top end greater than the distance to which the twoplanesof "threads of a lease .are separated verticallyiin forming a lease;

thatis'to say, at a distance from said end greaterfthan the' depth of a lease-shed, is a -pig-tail orf-spiral-eye 19 made from round-wire. The body combined with the spiral-eye constitutes the dent 17. Each spiral-eye has ascending anddescendingportions20and2l thatare laterally offset from the shank towardth'e front ofthecoinb, the

portion 20 being laterally opposite the body,

18 and the portion I 21 being, substantially, laterallyoppositeto a dent '16. I "tremity" 29 of the outer coil, of the eye follows theadjoining coil out of a vertical di- "rection and away from thespace'24 between dentsl6 and17 to prevent a thread in the The exspace 24 from being caught upon it. It is 'thengiven a short upward turn to facilitate the dent 1 6and the body 18 shall be of fiat- "wire or identical; that the spiral-eyes shall be made from round-wire or, that the dent l7 shall,be consti'uctediby uniting two separate pieces of metal", f i f g In threading the warper,one half 'of the threads 22 are each twisted intothe eye of a drop-wire 23 land dropped into. a space 24 between a dent 16 anda dent 17 where there is no spiral-eye. They are then led over the roll 25 to the thread-receiver (not shown); These threads 22are not'influenced by jmo- {tions'of thecornb. They need not be moved while taking a lease. The other half of the threads 26 are each twisted into the eye of a ion drop-wire 27, dropped into a space 28 between a dent l6 and a dent 17 where a spiral- .eye 19 is located, carried down past the spiral parts are given the positions of Fig. 3 with the cams and the comb in their middle positions. Intaking alease, the comb-box is moved alternately into. the position of Fig. 2 and that of Fig. 4,-and the lease-threads are inserted in the open sheds shown inFigs.

2 and 4 between the dents and the roll 25. To obtain the positions of Fig. 2 the cams are moved to their extreme right positions in Fig. 1. This carries the threads 26 above the threads 22. To obtain the positions of Fig. 4 the cams are moved to their extreme left positions in Fig. 1. This carries the threads 26 below the threads 22, but the plain upper portions of the dents 16'and 17 above the spiral eyes are of ample length to permit the comb-box to be lowered as in Fig. 4 without withdrawing the said upper portions from between the threads of the upper plane of the lease-shed. By reason of the fact that the free extremity of the spiral-eye is bentfrom-the sideofthe eye toward the middle of the width of the latter, as represented clearly in Figs. 1, 6 and 7, it follows that as the comb is raised and lowered and the spiral-eyes pass up and down between the threads occupying the alternating dent-sp aces, in shifting fromthe position shown in Fig. 4 to that shownin Fig. 2 and vice versa, there is no danger of thesaid free extremity catchingone of the latter threads. The form and construction of the spiral-eye are such as to prevent the threads on either side of the same from getting'into the eye in taking the lease. a On reference to Figs. 1 and 6 it will be observed .thatthe dents of the comb are alternately long and short, and that the spiral-eyes re-- spectively are mounted upon the long dents. The diilerence in the lengths, of the dents indicates to the operator which dents have the spiral-eyes, so that the operator will not have to look so long in putting the threads down into the comb-spaces and intothe eyes.

Relative to lease-combs of the prior art which are adapted for both elevating and depressing ,one set of threads with respect to another "set of threads, it is thoughtthat thelease-comb of this invention issuperior to any of the prior art in that it is stronger, more durable, and less expensive to manu-: facture than any prior-lease-comb which is so great a saver off-labor in. drawing-in a} I claim;

1. In a lease-comb, a dent having at an intermediate point its'height a spiral-eye for a thread and having above said eye a plain upward extension exceeding in length the depth of a lease-shed.

2. In a lease-comb, a flat dent having affixed thereto a spiral-eye of round wire.

3. In a lease-comb, a dent having a flat shank and having a spiral-eye.

' 4:. In a lease-comb, a dent having at an intermediate pointin'its height a spiral-eye having ascendingv and descending portions that are laterally oflsetfrom the shank.

5. In a lease-comb, a dent having at an intermediate point in its height a spiral-eye having ascending and descending portions that are laterally ofi'set fromthe shank, one such portion being in the lateral projection ofits shank upwardly extended.

6.. In a lease-comb, adent having at an intermediate point in its heighta spiral-eye of which the free extremity of the outer coil follows the adjoining coil out of a Vertical directionvand then projects above it.

7. In a lease-comb, a dent having an outstanding spiral-eye in combination with means folpreventing its rotation.

S. In a lease-combhaving spiral-springs,

the combination with the springs of dents? eachv having an outstanding spiral-eye and havmg means for preventmg the rotation of the dent located between the coils of the springs.

9. The combinationof a lease-comb box 3 provided with dents each having at an intermediatepoint in its height a spiral-eye and each having also abovesaid eye a plain upward extension .exceeding in length the depth-of a lease-shed, with the spaces between dents open at their upper ends to permit the threads to be dropped into the same, with-means for holding the box at different heights.

10. The combination of a lease-comb box, spiral springs located within the box, and flat dents alternating with dentseach having a flat shank and a spiraleye, the shanks of the dents located betweenthe coils ofthe springs, withthe spiral-eye located at an in- I termediate point in the height of its dent and with a plain upward extension above said eye exceeding in length the depth of a lease-shed, the spaces between dents being open at their upper ends to permit the threads-to be dropped into the same.

- 11, The combinationof a lease-comb having dentsrespectiv'ely provided at an intermediate point in the height thereof with a spiral-eye, and cams adapted for movement lengthwise'of the comb to change its elevation for forming a lease, each of said dents having above it's spiral-eye a plain upward extension exceeding in length'the depth of a Z lease-shed, the spaces between dents :being open at their upper ends to permit the the spaces between dents being open at'their c upper ends to permit the threads to be dropped into the same. a Y

13. A lease-comb comprising a series of flat dents alternating with dents each hav ing at an intermediatepoint an outstanding spiral-eye having ascending and descend- Gopies of this patent may be obtained for ing portions that are laterally ofifset from the shank, one such portion being substantially in the same plane with the body of the dent, and the dents having above said eyes plain upward extensions exceeding in length the depth of a lease-shed, the spaces between dents being open at their upper ends to permit threadsto be dropped into the same.

In testimony thereof, I 'afiix my signature in the presence of two witnesses.
